Development of Bridge Preservation Cost Models for Planning, Programming, and Budgeting

The preservation of existing highway systems continues to be a critical issue as various levels of government struggle to ensure acceptable performance in terms of facility conditions and levels of safety, security, and environmental impacts associated with system usage. The issue of bridge preservation assumes greater importance in the current era that is characterized by increased percentage of aged existing facilities, increasing travel demand and traffic loading, uncertainty of sustained funding, and increasing user expectations. In light of these trends, bridge managers seek management practices that are most cost-effective and in the best interests of taxpayers and highway users. A vital component of cost-effective bridge management is regular monitoring and updating of bridge preservation treatment costs. This paper presents bridge preservation cost models classified by treatment type (deck preservation, superstructure replacement, and bridge widening), bridge type (concrete slab and beam, and steel), and bridge component (deck, superstructure, and substructure), respectively. The analysis was conducted using data on bridge preservation contracts associated with the Indiana state highway network. This paper generally asserts that bridge physical characteristics such as material/construction type, length, and deck area are typically useful but may not always sufficient in deriving reliable estimates of bridge preservation costs. In many cases, these costs are also influenced by bridge condition or age at the time of preservation treatment. The developed cost models can be used by bridge managers and financial personnel as a guide to assess bridge preservation needs in long-term planning, programming, and budgeting.
